Open full text 8 citations

Abstract

A virtual prototype model of S195 diesel engine was established by using CAD, finite element analysis based on virtual prototype technology and dynamics theory of flexible multibody systems to study the kinetic discipline of the crank-rod mechanism,vibration of cylinder block caused by inertia force and the balance problem of inertia force.The rigid body and flexible body simulation were compared.The interaction force between components could be determined by flexible multibody dynamics analysis of the crankshaft system under the real working condition. The simulation results are accordant with those in true working state of S195 diesel engine. This research provides a feasible advanced method for design and development of diesel engine.
